✋ Kale

Kale is not safe for dogs to eat because it contains several potentially harmful natural compounds, including calcium oxalate and isothiocyanates. Calcium oxalate can cause health issues such as kidney disease and bladder stones, and dogs that are prone to kidney or bladder stones are especially prone to developing health complications from ingesting this compound. Isothiocyanates, which are also found in broccoli, can cause mild to potentially severe gastric irritation, and should be avoided as a regular treat. Kale can also interfere with thyroid function if fed on a regular basis. Dogs should not eat kale regularly, but accidentally eating a kale rib is unlikely to harm your dog.

Tips

When sharing food with dogs, it is important to keep a few things in mind:
  • Ask your veterinarian before feeding your dog anything—especially if they take medication or have any medical conditions (e.g. diabetes, allergies, etc.). Some medication can interact with foods, so don't take any chances!
  • Any foods dogs are eating for the first time should be introduced in small quantities. Monitor them after they eat it, and if they experience any negative symptoms, don't feed it to them again.
  • Any foods outside of your dog's normal diet should make up less than 10% of their daily food intake. For example, if your dog eats 5 cups of food per day, they shouldn't eat more than ½ cup of treats (e.g. ¼ cup of blueberries, and a couple of baby carrots). Any foods fed to dogs in large amounts can lead to digestive upset, so moderation is truly key.
  • Any foods shared with dogs should be cut into bite-size pieces, with all choking hazards removed (e.g. pits, peels, seeds). These choking hazards can even become obstructed in your dogs gastrointestinal tract. Never share these things with dogs, even if they are perfectly normal for humans to eat.
  • Dogs shouldn't eat foods with added salt, oils, sugar, seasonings, sauces, or any other variations. These additions, while delicious, often contain ingredients that are harmful, if not toxic to dogs, such as garlic, onions, or even xylitol. Dogs should not eat foods that were prepared with these ingredients, either.
  • Dogs shouldn't eat high fat foods, even if they are generally considered healthy for us. Dogs aren't built to eat large amounts of fat and these foods can cause dogs to get gastrointestinal upset and even pancreatitis, an inflammation of the pancreas which can range from mild to severe. Symptoms are usually vomiting, lethargy, diarrhea, and a loss of appetite. This can be an emergency situation and requires immediate veterinary treatment.
  • Dogs shouldn't eat processed foods such as baked foods, boxed snacks, fast food, etc. Aside from being unhealthy and high in fat, they often conceal ingredients that may be troublesome or even toxic for dogs, such as a sweetener called xylitol. Be sure to thoroughly read the ingredients of any processed foods you share with your dog, and if you can't determine the safety level of each ingredient, do not share it with your dog.
  • Dogs shouldn't eat canned versions of foods (e.g. fruits, vegetables, etc.), due to their added preservatives including excess salt and sugar, which can be harmful to dogs (and humans!). Choose fresh or even frozen versions instead.
  • Recent research suggests that several foods, such as peas, legumes, and potatoes, while not toxic, may not be appropriate for dogs to consume regularly, due to their correlation with the development of a heart condition called canine dilated cardiomyopathy (DCM).
